DEI Protect A Boot universal 6 inch sleeves pair

These DEI sleeves fit around spark plug boots to place a textile heat barrier between them and engine compartment heat. Their treated glass fibre forms a double wall, with an internal metal ring fitted at the base of each sleeve.

This version is 6 inches long, approximately 15 cm, with a 1 inch internal diameter, equivalent to 25.4 mm. The pair is available in silver, black or red. The price covers two sleeves of the same colour; spark plugs, boots and wires are not included.

Universal fit applies to straight and 45°/135° plug boots compatible with these dimensions. Check diameter, clearance and routing before installation. For tight bends or thicker boots, the manufacturer recommends other ringless versions, so this offer does not guarantee fitment to every engine or plug boot.
